Mindfulness meditation programs have shown promise for the treatment of anxiety, one of the most common mental health disorders in the US. New research suggests people can begin to derive psychological and physiological benefits from the practice after a single introductory session.
Nuclear fusion, the process that powers our sun, happens when nuclear reactions between light elements produce heavier ones. It's also happening -- at a smaller scale -- in a Colorado State University laboratory. Using a compact but powerful laser to heat arrays of ordered nanowires, CSU scientists and collaborators have demonstrated micro-scale nuclear fusion in the lab. They have achieved record-setting efficiency for the generation of neutrons -- chargeless sub-atomic particles resulting from the fusion process.
